Goodmorning everybody, I've installed pi-hole as DNS for my home network behind an OPNsense router following this guide Install Pi-hole on a Raspberry Pi with Docker and Portainer - Home Network Guy.
Everything works fine but: I have in my countryhouse a CCTV (from Reolink). When I connect to the camera from the app I see in top permitted domains a lot of p2p1.reolink.com, p2p2.reolink.com, p2p3.reolink.com and this is a long list that doesn't permitt to see other domains 
Is il possible to group all .reolink.com in a single row and how?
Thank you so much!!!!!
Nobody can help me in understanding how to configure it?
thank you!
No this is not possible yet. There is an open feature requests on that
BUT you can hide all *reolink.com domains from the top permitted domains by adding it here:
Thank you so much! Will try with second choice, waiting for the feature to be implemented.
Hi yubiuser, I've tried to add the domain following your instructions but, when I save, domain disapperars from the list and I still see the domain in Top Permitted". It seems not saving the configuration...
That clearly should not happen. Was there any error indication?
On success the message should look like this.
Try to clear your browser's cache and try again.
If still not successful, look for errors in
